From the looks of it, there are no stand-offs around the edges of the Sentraq case, and also that case doesn't accommodate riser feet. This case has a few stand-off around the perimeter (probably doesn't make too much of a difference), and has the countersunk holes for feet.

You're probably better off ordering from Aliexpress tbh, depending on where in the world you live, it might come out a little bit cheaper (for example ordering to the UK from Aliexpress saves about £5 compared to getting it from here, not to mention customs fees might put that figure even higher)

AliExpress can definitely work out in your favor but it is important to note that is basically their version of Ebay. There are a fair amount of scammers so you should always cover your ass. Make sure it is a reputable seller and make your payment as secure as possible with the ability to get your $ back should something go wrong.

Actually the Aliexpress version http://www.aliexpress.com/store/product/Wholesales-GH60-Anodizing-Aluminum-Case-for-60-Mechanical-Gaming-Keyboard-Compatible-Poker2-Pok3r-Faceu-60/429151_32540926035.html

is exactly the same and I wouldn't be too surprised if Massdrop is sourcing these from them. And you wouldn't have to wait couple months for it to ship either.
